Anyone know what the mixing ratio by weight is for their surfacing wax? Also how long do I have to wait before I start sanding this stuff? Its been low 80's and the humidity is near 100%.

at that heat and humity levels i would wait or make sure your dryer is 100% working and wont let any moisture through..also use a few air hose's and go high and low around your shop with the host to trap ant moisture..with your scale i would not go more that 2% at 80+ degrees..then wipe over the dried surgace real quick with acitone to get rid of some of the way..you can start the next day and just brake it down and leave it sit for a week or so and then buff it..

This should tell you what you need as far as the ratio:
